A California company has recalled more than 90 tons of prepackaged salads and sandwich wraps because they may be contaminated with a toxin-producing strain of E. coli, the U.S. Department of Agriculture said. Glass Onion Catering in Richmond, Calif., is recalling ready-to-eat salads and wraps with cooked chicken and ham that may contain E. coli O157:H7, the department’s Food Safety and Inspection Service said. The products have been linked to 26 ill patients in three states, the Centers for Disease Control and Prevention said, most of them in California. A full list of recalled products, some packaged under the name Atherstone Fine Foods, is available on the Food and Drug Administration’s website.
